Local Environmental Conditions
This area, close to home here, has hazel and willow crowd the water's edge, both classic sources of early allergenic pollen. Here, a short distance from here, a wooded area built around oak and birch, both contributing heavily to the region's spring pollen totals. Seasonal timing here generally tracks the wider region, give or take a week or so.
Near the bank, hazel and willow lead the seasonal calendar, starting well before the main spring rush, topping out around March. The area's oak and birch trees pollinate through mid-to-late spring, usually peaking from April into May. As spring turns to summer, grass pollen rises toward its June high, then yields to ragweed, the dominant late-summer and fall allergen through October.

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
